Work Word Problems

"It is possible to solve word problems when two people are doing a work job together by solving systems of equations. To solve a work word problem, multiply the hourly rate of the two people working t ...

Why SSA and AAA Don't Work as Congruence Shortcuts

"Four shortcuts allow students to know two triangles must be congruent: SSS, SAS, ASA, and AAS. Knowing only side-side-angle (SSA) does not work because the unknown side could be located in two differ ...

Wavelength

"Wavelength is the distance between two crests of a wave. It is related to frequency and period by the equations wave speed = frequency x wavelength and wave speed = wavelength / period." Fuente: Brig ...

Wave Speed

"Wave speed is the speed at which a wave travels. Wave speed is related to wavelength, frequency, and period by the equation wave speed = frequency x wavelength. The most commonly used wave speed is t ...

Wave Phase

"Wave phase is the offset of a wave from a given point. When two waves cross paths, they either cancel each other out or compliment each other, depending on their phase. These effects are called const ...

Wave Inversion

"Wave inversion occurs when a traveling wave is flipped upside down when being reflected back into the old medium. This happens during the process of a wave moving through one medium encounters a boun ...

Wave Characteristics

"Waves are disturbances that travel through a fluid medium. Several common wave characteristics include frequency, period, wavelength, and amplitude. There are two main type of waves, transverse waves ...

Wave Beats

"Wave beats are sounds produced by the combination of two waves with almost the same frequencies. Wave beats are caused by wave interference. " Fuente: BrightStormWave Beats es un video-tutorial (en i ...

VSPER Model

"The VSEPR model stands for Valence Shell Electron Pair Repulsion model. The VSEPR model is a model which predicts the geometrical shapes of molecules based on the repulsion between their lone pairs. ...

Vertical Angles

"Vertical angles always come in pairs. They share a common vertex but they cannot share a side. Vertical angles are congruent, which means they have equal measures." Fuente: BrightStormVertical Angl ...
